I want to utilize resurrection or blind date dialog for choosing amounts of money, but can't figure out a way to change text strings. I start to suspect they're somewhat hardcoded, but I really hope someone knows a way.

You've found the right type of dialog for that ? Which one did you choose ? Is it "Dating Services" (1F) ? If I knew, I could try to help you.
Anyway, the string of a dialog is number 12D (but you seem to know already)

Yes, I tried Dating Services and Resurrectonomitron (1B). They don't seem to look at pointed strings at all (I use the wizard).
I also tried the one for ordering food, but that one didn't show amount of money, so above two seem more convenient so far.

I've had the same problem with a project of mine. The dialogs seem to use the sim string (My object). So I used the Run Tree by name, so that the references could be different (My object and perhaps stack object). It works for some, not for all. Once, I just opened then resaved it, and it worked. I think the wizard don't work sometimes, you have to change the operands themselves.
It's just suggestions, you'll have to test a few times.
I'll try on my own if I have time.

Let me clarify about that RTBN trick. Are you saying that you were able to change texts for one of these dialogs (Dating Services or Resurrectonomitron) or some other dialogs?

No ! It would have been THE solution. Unfortunately, it was another one, but I was thinking that it might the same "referencing" problem.

Edit : I've tried dates service by curiosity. My solution doesn't apply at all. The texts doesn't change at all. I've tried to find the string and couldn't. After some research and testing, in my opinion, it can't be changed. The solution might be in the LUA, and it is hard to change. I know only of Chris Hatch to be able to change LUAs (I think I remember him saying it, but I could have made a mistake)

@gdayars, the one that appears when you buy groceries? It doesn't show correct amount in numbers for some reason. When I drag a bar, numbers go from 1 to 2. In other words, I failed to make this dialog usable and I'm not sure why.

This topic needs closure, so here goes.
I found a way to change the resurrection dialog text. Hunted it down to the program files =) It's in UItext and it can be modded without replacing the core file itself (yay).
And thanks, gdayars, I peeked into Insimenator and figured out what I did wrong with the food one.
Now if only it was easy for the game to manage large numbers above 32767...
